This invention relates to a hair shaping device,

particularly adapted for curling the" hair in pin curls.

It is a primary object of this invention to provide a simple devicewhereby hair may be'quickly I wound into the necessary spiral curl orcoils and supported in place upon the head during the curling of thehair.

Another object of this invention is to provide a device of the charactermentioned above which can be manipulated by inexperienced persons with aminimum liability of damage to the hair, and a minimum liability ofcausing discomfort.

Yet another object of this invention is to provide a device for curlingthe hair, which in the hands of hairdressers may be operated with greatrapidity, and an attractive coifiure achieved as a result of a fewminutes work.

Yet another object of this invention is to provide a device forproduction of pin curls, wherein the application of solution to thecurls is facilitated, and whereby the application is made possible atthe exact location necessary to assure a perfect setting of the curls.

A specific object of this invention, of no less importance than thepreceding objects, is to provide improved means for releasing the coilof hair after the curling operation has been completed.

A still further object of this invention is to provide a device forproducing pin curls, wherein means is provided to prevent breaking ofthe hair during the use of the device.

A last object to be mentioned specifically is to provide a device ofthis character which is relatively inexpensive and practical tomanufacture, which is easily manipulatable due to its light weight andsimple construction and the simplicity of the actual compressing andreleasing of the coils of hair, the lightness of weight being achievedby producing the device from plastic material which is slightlyresilient, one such plastic material being Lucite, although any suitableplastic material which is unaffected by solution used in setting hairmay be used.

With these objects definitely in view, this invention resides in certainnovel features of construction, combination and arrangement of elementsand portions as will be hereinafter described in detail in thespecification, and particularly pointed out in the appended claim, andillustrated in the accompanying drawings which form a material part ofthis application, and in which:

Figure 1 is a view in perspective of the as- 1 Claim. (01. 132-33)sembled device, the sleeve being partly withdrawn and the disc with itstubular handle being also partly withdrawn from the cup;

.Figure 2 is a vertical sectional view taken on a longitudinal centerline;

Figure 3 is an exploded view of the device. showing a lock of haircoiled around the sleeve and representing an initial step in the processof producing a pin curl by the employment of this invention;

Figure 4 is a view of the device with a lock of hair compressed withinthe cup, preparatory to the application of setting solution to the hair;and

Figure 5 is a similar view showing how the sleeve is used to release thecoil of hair from the cup, after the setting operation has beencompleted.

Similar characters of reference designate similar or identical elementsand portions throughout the specification and throughout the differentviews in the drawings.

Referring now to the drawings in detail, this invention includes a cupgenerally indicated at H] and comprising a hollow cylinder with a sidewall (2 and an end plate 14. A longitudinal slot I6 is provided in theside wall I2 and this slot is continued radially into the end plate M.This slot allows the insertion of a lock of hair into the cup In. Anaxial spindle I8 is rigidly or integrally secured to the inner surfaceof the end plate [4 and extends well beyond the mouth of the cup I0.Upon this spindle I8 is a sleeve 2|], the sleeve being axially andfrictionally slidably mounted on the spindle so that the sleeve willremain in adjusted position relative to the spindle while allowingreasonably easy removal thereof, as during the release of the coils ofhair from the cup 10 in the last stages of the setting operation. Thesleeve 20 may be of a length comparable to the length of the spindle l8and must be considerably longer than the longitudinal depth dimension ofthe cup ID. The outer end of the sleeve 20, indicated by the numeral 22,is longitudinally slitted as indicated at 24, this slitting of the endportion 22 of the sleeve facilitating the attainment of a properfrictional coefiicient between the sleeve and the spindle 18.

A disc 26 of a diameter only slightly less than the internal diameter ofthe cup I0 is provided with a plurality of apertures 28"and this disc ispreferably integral with a tubular handle 30. The tubular handle 30 isaxially and frictionally slidably mounted upon the sleeve 20, the outerend of the handle 30 being slitted at 32. It is an important feature ofthis invention that the coefiicient of friction between the tubularhandle 30 and the sleeve 20 must be less than the coeflicient offriction between the sleeve 20 and the spindle [8, so that in theremoval of the device from the hair, the tubular handle and disc willeasily slide from the sleeve, leaving the sleeve substantially in theposition indicated in Figure 3 until the tubular handle and disc arecompletely removed from the device, whereafter the sleeve 20 is pulledaxially to facilitate the uncoiling of the hair from the cup [0.

The operation of this invention will be clearly understood from aconsideration of the foregoing description of the mechanical detailsthereof, taken in connection with the above recited objects and theillustrative drawing. In recapitulation, and by way of furtherexplanation, the method of use of this invention involves the followingsteps, in the order named. The lock of hair is first wrapped around thesleeve with the fingers, the sleeve being positioned on the spindle iii,in the position indicated in Figure 3, which figure may be considered asrepresenting the first step in this process. The coils of hair are thenpressed into the cup [0, this being accomplished manually. The next stepis the insertion of the disc 26 and tubular handle 30 upon the sleeve,the disc forcing the coils of hair into the cup as indicated in Figure4. Solution is then applied to the coils through the slot in the cup andthrough the apertures 28 in the disc 26. The second last step is theremoval of the disc 26 and tubular sleeve 36, this step beingaccomplished, of course, after a certain length of time has elapsed toallow the hair to set. Finally, the coils of hair. which may now beproperly considered as curls, are released by pulling the sleeve 20axially from the spindle l8, as illustrated in Figure 5. The action ofthe sleeve 20 is, as mentioned above, an important feature of thisinvention inasmuch as the releasing of the curls can be difficult toaccomplish unless a special means is provided to pull the curl from thecup without damaging the hair, a function achieved perfectly by thesleeve 20.

Obviously minor variations from the embodiment of this inventionillustrated and described herein may be resorted to without departurefrom the spirit of this invention.

Having described the claimed as new is:

A hair shaping device including a, cylindrical cup comprising an endplate and a side wall, and a mouth opposite said end plate, said sideWall and end plate having a slot with an open end at said mouth, aspindle secured to the inner face of said end plate and extendingaxially of the cup beyond' said mouth, a sleeve axially and frictionallyslidably mounted on said spindle and of a length greater than thelongitudinal depth of said cup a fiat, apertured disc of a diameterslightly less than the internal diameter of the cup, and a tubularhandle axially and frictionally slidably mounted on said sleeve andcarrying said disc on the end of the tubular handle adjacent the endplate of the cup, the coefilcient of friction between the tubular handleand. said sleeve being less than the coefficient of friction between thesleeve and the spindle.
